I don't have much luck with taking cuttings of Nepenthes, but I do find air layering works well for me. So here is a brief photo guide on how to do it:

The reason for layering can often be to increase the number of plants, but for me it is to stop the plants outgrowing the terrarium where they live, and having spare plants as a result is a bonus which I can then swap for other specimens. Choose the stem you want to layer. Cut off a leaf at the point where you want to do a layer, as in this photo:

Press a few stems of Sphagnum into the cut. This is to keep the cut open and stop it from healing up. I have tried doing notches before, but find this "wedged cut" works much better. Some people like to use hormone rooting powder, although it never seems to work for me. There has been a recent suggestion that rooting powder may work better on layerings done towards the top of vine because of the particular hormone balance near the shoot tips... I tend to do mine towards the bottom of the vine, which may explain why hormones do not help:

Next wrap some damp Sphagnum moss around the cut. You do not need very much, a ping-pong ball size is as much as you will ever need and usually much less than this. Wrap a piece of clear plastic (e.g. cling film) around this Sphagnum, and secure top and bottom with ties. Leave the top tie slightly loose to allow water in, you do not want the moss to dry out. You may need to water the moss occasionally with a syringe or pipette to keep it damp:

Several weeks later, you may see roots growing under the plastic, Nepenthes roots are black. In this picture you can see Nepenthes roots growing in the crease of the plastic at the bottom of the wrapping. When you see the roots, you know the layering has rooted and you can cut it off:

I would like to do the same with my Neps but they don't have any upper part of the steam without pitchers. Can I airlayer it with them?
And second...what if I don't have steams of Sphagnum, can I use something else??

thank you

you can airlayer any stem. any dap compost will do, vermiculite or similar may work.

I used your guide and tryed my own little spin on it. When slicing the stem, I went further "in", pretty much in the middle of the stem, and I made the cut at a very shallow angle (probably about 5° from the horizontal), about 1" long. I also dusted the sphagnum that went in the cut with rooting hormone. This did not speed up the rooting process any, though it did create wayyy more roots. A side effect of this though, was that the roots were only about 1" long, though there were probably 30 +/- of them

Prozac, this way, the plant itself already has roots, but new roots are gorwn out of where the cut is made. It takes shorter, due to the cut area still having some sort of vascular system still attached. Also, if you make a cutting and it dies...sucks for you. If you make an airlayering (sp?) and it doesnt work, all that happens is the stem heals up and the plant continues as it was
